WATCH: Damir Dzumhur's freak collision with a ballboy (all is well)

Damir Dzumhur, the No. 26 seed at Roland Garros, didn't make many mistakes early in his third-round match against second-seeded Alexander Zverev. The game's highest-ranked Bosnian player won two of the first three sets with fleet feet, creative shotmaking and the requisite stamina needed to succeed on clay.
